General
high-molecular-weight dispersing agent
Efka® PU 4010 is a polymeric dispersant for stabilizing inorganic pigments including carbon blacks. It also has an excellent performance in many organic pigments. This results in:
• reduced grinding time
• improved gloss
• prevention of flooding and floating
• higher color strength
Due to its particularly good combination of price and performance,Efka® PU 4010 is a very attractive substitute for conventional wettingand dispersing agents.
It is possible to mix combinations of inorganic pigments stabilized with Efka® PU 4010 and organic pigments stabilized with other Efka® highmolecular-weight polymeric dispersants.

Selection Guide
Efka® PU 4010 is a strong choice when your formulation is built around carbon black or other inorganic pigments and you need reduced grinding time, higher color strength, and resistance to flooding and floating. Its price-to-performance profile makes it a practical substitute for conventional wetting and dispersing agents, and it can be combined with other Efka high-molecular-weight dispersants when formulating mixed inorganic/organic pigment systems. Contact our technical team with your pigment type and target performance for dosage guidance.

Why Sourcing Consistency Matters for Buyers
Because grinding time, gloss, and color strength depend on consistent dispersant performance, buyers should confirm current specifications for this dispersant against the latest technical data sheet before scheduling a production run. A supplier that consistently delivers this product to its stated active ingredient content and viscosity profile reduces the need to re-qualify a pigment dispersion recipe with every new batch.
This is particularly relevant for formulators producing solvent-borne and high-solids industrial coatings at volume, where dispersant consistency is directly tied to gloss, color strength, and resistance to flooding and floating. Buyers should confirm current batch documentation for this dispersant against the latest technical data sheet before finalizing a production schedule.
What to Consider When Sourcing Efka PU 4010
Buyers evaluating this dispersant for the first time should confirm compatibility with their specific pigment system, since performance can vary between purely inorganic, purely organic, and mixed pigment formulations. Requesting the current certificate of analysis alongside the technical data sheet is a practical way to confirm that a given batch matches the manufacturer’s published active ingredient content and typical property values.
Packaging format, minimum order quantity, and shipping method should also be confirmed directly with the supplier, since these factors affect how this dispersant reaches a production facility. Buyers sourcing this dispersant for time-sensitive coating or printing ink production schedules should discuss lead time and logistics requirements before finalizing an order.
General Handling and Storage Guidance
As with other solvent-based polymeric dispersants, this dispersant should be stored in accordance with the supplier’s technical data sheet and safety data sheet, typically in a cool, dry, well-ventilated area away from direct sunlight and sources of ignition, since its flash point of 24 degrees C means standard solvent-handling precautions apply. Personnel handling this material should follow the procedures specified in the safety data sheet.
Buyers should request and review the current safety data sheet for Efka PU 4010 prior to receipt, and confirm that on-site storage conditions are compatible with the supplier’s recommended shelf life and temperature range. Proper inventory rotation helps maintain the color strength and gloss performance described above.
